    I’m midway through architecting a new system and I’d like a capable full-stack developer to pair with me day-to-day. The immediate focus is front-end development, so you’ll be steering our React and layers—building reusable components, wiring pages to the router, and tightening up state management. While the UI comes first, we will also expose fresh endpoints as we go; you’ll help shape the Node.js / API that feeds those screens. We already have a rough domain model running in Java micro-services, so expect to consume and occasionally extend those services rather than start from scratch. Clean, well-tested code, Git-based collaboration and clear commit messages are essential because we’ll be working side-by-side and merging often. Deliverables (acc...

    Oil pipelines are commonly buried 3–5 feet beneath riverbeds to protect them from environmental exposure and mechanical damage. However, riverbed scour and sediment transport during floods or strong flow events may remove sediment and potentially expose the buried pipeline. Continuous monitoring of riverbed elevation is therefore essential to ensure pipeline safety and to understand sediment dynamics. This project proposes a Smart Rock monitoring system designed to measure riverbed scour and elevation changes. Each Smart Rock contains an embedded absolute pressure sensor that measures water pressure to estimate local water depth. By combining these measurements with the absolute water surface elevation, the absolute elevation of each Smart Rock can be determined. Since the pipeline ...
